There are so many caveats on pg_migrator (and things that need to be
done after the migration is complete) that one starts to wonder if
people is not better off just using parallel pg_restore. From Stefan's
reported timings I'm not sure that pg_migrator is that much of a benefit
in the first place ... unless copy mode can be made much faster. (On
link mode it is so much faster that it's worth it, but then you don't
have an escape hatch).
